Tl DE-WATER ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 241,937, dated May 24,1881.

Application tiled June 25, 1880. (No model.)

.To all whom it may concern:

Beit known that I, ROBERT GREUZBAUR, of the city of Brooklyn, E. D., inthe county ot' Kings and State of New York, have invented 5 a new anduseful combination of mechanism for raisin g waterby the force ot' thetide, named the Tide-Water Elevator,7 which is fully described in thefollowing specification, reference being had to the accompanyingdrawings.

The principal object of my invention is to raise water on andneartide-watereoasts,bays, inlets, and rivers, to be applied tocleansing house-closets and drains, to the liushing ot' sewers, forsprinkling streets, and for manufacturingandotherpurposes.Iaccomplishthe Object by causing the hood-tide to store water in areservoir, this stored water beingy prevented from returning with theebb-tide by a self-closin g valve. When a sufficient head or differenceot' level is established between the stored water and the ebbtide achannel is opened, which admits the stored water to a hydraulic ram orother water-elevatin g mechanism, which delivers the water wheredesired.

5 In the accompanying drawings, Figure l is a sectional elevation of mytide-water elevator, and Fig. 2 is a sectional elevation of a modifi'cation of a portion of the saine.

InFig. 1, A is a pipe or drain through which the tide-water flows intothe large reservoir B, the pressure ci' theincomin g water forcing openthe valve O,which may be made so as to be very little heavier thanwater, being made hollow, or loaded with cork, or made of lightmaterial, so that the Water in the reservoir B will attain nearly ashigh a level as the tide. When the tide recedes the valve C closes andprevents the escape ot' the water from the tank B.

D is a large pipe or a small tank, in which the tide rises and fallsfreely through the branch pipe d', connecting with pipe A. This pipe ortank D may be inside of the reservoir B, as shown, or it may be outsideand separate from it. In this pipe D a lioat, F, operates, attached torod E, which rod is attached to centrally-pivoted lever G, the other endof lever G being attached to valve H, which controls the entrance intodrive-pipe'l, which feeds the hydraulic ram R. Therwater raised by theram Rpa'sses through the pipe K to its destination. The loat F may bevertically adjusta- I ble upon rod E by nuts?? a.

Fig. l shows the ram Rinoperative, the valve H being closed by the ioatFthrough its tendency to rise with the water entering tank D. DuringebbAtide the valve O remains closed, and as soon as the tide hassuliiciently receded the weight of tloatF, when no longer sustained bythe water, overcomes the weight of valve H with its attachments, as wellas the pressure ot' the water upon the saine. Assoon as valve H ispartly open the water-pressure upon the same is sutticiently balanced tocause the iioat F to descend suddenly andsufcien tl y to throw valve Hwide open, thus setting the ram into instant-operation. The float F neednot be a body or vessel lighter than water and able to float upon theSallie, but may be simply a dis placer of water, as a piece of wood,iron, or of any other substance, a correspondingdisplacer, G', beingattached to the outlet-valve H of such relative weight that when bothbodies F and G' are submerged the valve H, with its displacer G andattachments, will be heavy enough to seat. When the water has recededfrom displacer or float F, leaving it dry, a weight equal to the body ofwater displaced by F and its attach ments will be acting in overcomingthe overweight of valve H and its displacer Gl and attachments, as wellas the pressure ot' the water upon the valve H. For instance, the valvehaving an area ot' twenty square inches and the depth of Water upon itbeing twenty-eight inches, the water displaced by iioatordisplacer Fmust be over twenty pounds, added to the weight necessary to overcometheoverweight of valveH and its attachments.

The reservoir B is best made large enough, so that its water-level willnot fall very much during the operation of the ram in order to prolongits operation under a good head.

Instead ot' the float F and lever G, or of two displacers, G and F, androekbeam G, with their attachments, the arrangement shown in Fig. 2 maybe used.

The small tankD adjoins the res'ervoirB, with a ilat partition, d2,between the two, into which a flexible diaphragm, M, is inserted at aproper height, and centrally pivoted by rod m' to the upright arm h' ofvalve H. While the water stands equally high in tanks B andD, thisdiaphragm M stands centrally and the valve H is closed. When the waterhas receded sufficiently from tank D to uncover the diaphragm IOC moreor less on that side, the pressure of the water in reservoir B willforce the diaphragm into the position shown, thus opening valve ll. Asthepressure ot' the water upon valve H before its opening will give agreater resistance than when through its opening that pressureis nolonger unbalanced, the diaphragm M, upon the opening ofthe valve H, willsuddenlvv move farther in toward tank I), thus throwing valve H wideopen. When the diaphragm M becomes suiciently uncovered on the reservoirB side also, the diaphragm returns to its central po. sition, aided bythe weight of valve il.

The inlet into pipe l should be protected by a large strainer, N, Fig.1, to prevent the entrance of obstructions into the ram.

The float F, insteadof being in apipeortank, D, may be anywhere inunobstructed tide-water.

The details can be varied according to eircumstanees and in man",v ways.

I do not claim in an artilicial spring or bulk head an underground draincombined with a hydraulic ram and a drive-pipe which receives water froma reservoir suitably located in the drain, the waste water ol" the ramand ot' the reservoir heilig discharged into a continuation of the drainwhich extends past the ram; but

Vilhat I claim as my invention is- 1. The combination, with a reservoirand a valve or gate through which it is supplied with water bydood-tide, but which is closed during ebb-tide, of a hydraulic rain anddrive-pipe adapted to receive water from said reservoir and to deliverit in eleva-ted positions, substantially as herein described.

L. The combination, with a reservoir and a valve or gate through whichitis supplied with water by iloodtide, but which is closed duringebbtide, ol' a hydraulic ram adapted to deliver water at elevatedpositions, a drive-pipe for ieeding said rain from said reservoir, and avalve which admits water from said reservoir to said pipe, and which isautomatically controlled and periodically closed and opened by mechanismoperated by the rising and falling of' the tide, substantially as hereindescribed.

3. The combination ot'storage-basin B with inlet A, valve C, valve H,auxiliary tank D, displaeers G and F, rock-beam Gr, channel l, andwater-raising mechanism R, with their con` nections and appurtenances,operating conjointly substantialb` as described.
